Citizen Science, Entomology, Inventory, Lepidoptera, Protected areas


The biogeographical importance of Dalmatia, bordered by the Dinaric Alps and the Adriatic Sea, is evident through the rich biodiversity of this region and its network of protected areas. One of those areas, Krka National Park (NP), supports a wide range of natural habitats, but rapidly increasing tourism puts high pressure on its ecosystems, despite its protected status. Accurate knowledge of species and their distributions within natural places such as Krka is essential to direct and prioritize future conservation efforts. As collecting biodiversity data is time and resource-intensive, alternative ways to obtain this information are needed. One possibility is monitoring based on eco-volunteering. From June to August of 2019, an Operation Wallacea/BIOTA scientific team surveyed a section of Krka NP and its surrounding boundaries, within the vicinity of the village of Puljane, to study its butterfly richness and abundance. Pollard walks and static count surveys were conducted with the help of eco-volunteers, testing the effectiveness of gathering field data through this approach. Overall, 57 butterfly species were found throughout the study, including four new records for Krka NP. Three further new species for the park were detected close to its boundaries and are also expected to occur within its borders. Here, we present an updated butterfly checklist for Krka NP, highlighting the positive impact of eco-volunteering initiatives and the importance of combined research efforts to study and protect the rich biodiversity and ecosystems of protected areas.
